Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+
) and chloride (Cl−
) ions). Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about −2 °C (28 °F). The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured −2.6 °C (27.3 °F). Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.

Is it a good idea to drink sea water if you're stranded on a desert coastline and facing dehydration? Find the answer in this video! The answer is based on the concept of Osmosis in which the molecules of a solvent tend to pass through a semi permeable membrane from a less concentrated solution into a more concentrated one. ► Production Team Creator - Omkar Bhagat http://fb.com/omkarbhagat Narration - Haley Anne Chamberlain Nelson http://youtube.com/untamedscience ► Website and Social Links Twitter - http://twitter.com/thecuriousenggr Facebook - http://fb.com/thecuriousengineer Google+ - http://gplus.to/omkar4 Website - http://thecuriousengineer.org ► Attribution and Credits | Copyright Stuff Brightly Fancy Kevin MacLeod (incompetech.com) http://incompetech.com/music/royalty-free/...
CASE STUDY: Desalination is a complicated process, the Seven Seas Corp.* approached DaVinci Studio to develop an animation that simplified the explanation of the process. Taking a cue from Seven Seas we started with squiggly style animation to give the technical looking components a non-technical look. Bottom line is to go from engineering-speak to the layman's level. Desalination (also called "desalinization" and "desalting") is the process of removing dissolved salts from water, thus producing fresh water from seawater or brackish water. Desalting technologies can be used for many applications. The most prevalent use is to produce potable water from saline water for domestic or municipal purposes.

Access to clean drinking water is a huge problem in the world, and leads to millions of deaths a year. Scientists have tried to work on the problem, finding ways to make water otherwise unsafe to drink potable. There's a the membrane technique-- but it's very expensive and not a viable option in water-stressed areas. There's a new idea from the University of Texas at Austin in the form of a small chip that neutralizes chloride ions at the microscale, desalinating the water. It's promising...but is the tech there yet? Kim Horcher and science educator Cara Santa Maria discuss the new development.

http://www.ted.com The world needs clean water, and more and more, we're pulling it from the oceans, desalinating it, and drinking it. But what to do with the salty brine left behind? In this intriguing short talk, TED Fellow Damian Palin proposes an idea: Mine it for other minerals we need, with the help of some collaborative metal-munching bacteria. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes.

Snorkeling at Sibuan Island, Semporna. Video was taken with my Xperia Z1. Update June 2014 My phone did not survive the second attempt into the sea. I went to the same spot a few months after this video was taken. Sadly, it lasted only few minutes under the sea water before it went black. Therefore, bring your Z1 into sea water on your own risk. I am not responsible for any damage caused.

I've got you under my skin
I've got you deep in the heart of me
So deep in my heart that you're really a part of me
I've got you under my skin
I've tried so not to give in
I said to myself this affair won't go so well
But why should I try to resist when baby I know more
than well
I've got you under my skin
I've got you under my skin
And I've got you deep in the heart of me
So deep in my heart that you're really a part of me
I've got you under my skin
I'd sacrifice anything come what might
For the sake of having you near
In spite of a warning voice that comes in the night
And repeats, repeats in my ear
Don't you know fool you can never win
Use your mentality wake to reality
But each time that I do
Just the thought of you makes me stop before I begin
'Cause I've got you under my skin
I've got you under my skin
I've got you deep in the heart of me
So deep in my heart that you're really a part of me
'Cause I've got you under my skin
oooohhhh
ooohhh ooohhh
oooohhhh
ooohhh ooohhh
I've got you under my skin
I've got you deep in the heart of me
So deep in my heart that you're really a part of me
